Three-valve manifolds

Badotherm three-valve manifolds can be used for isolating, calibrating, and testing differential pressure instruments. Manifolds can be mounted directly to the pressure instrument or remotely using a pressure tube. Depending on the type, the three-valve manifold can be supplied with or without a purge connection. All Badotherm manifolds are made of standard stainless steel and are also available in exotic materials such as alloy C276 and alloy 400. This manifold features a non-rotating conical tip to ensure perfect alignment. Badotherm manifolds are manufactured in the EU.

The valve spindle assembly consists of various components. All non-wetted parts are made of AISI 316 (L). All wetted parts match the body material. The cover is secured with a locking pin to the main valve body. The spindle has a safety backseat that prevents accidental spindle removal.

Needle valve for pressure instruments

Badotherm needle valves can be used to shut off impulse lines, isolate pressure instruments, or connect vents and drains on flushing flanges. All Badotherm valves are made of standard AISI 316 (L) stainless steel and are also available in exotic materials such as alloy C276 and alloy 400. This valve features a non-rotating conical tip to ensure perfect alignment. Badotherm valves are manufactured in the EU.

High Temperature Diaphragm Seal HTDS

Art. HTDS

Badotherm has developed a diaphragm seal capable of measuring pressure at process temperatures up to 600°C. To ensure proper operation, the diaphragm seal utilizes a revolutionary new design and principle at such extreme process temperatures. The design's innovation lies in Badotherm's patent for a high-temperature diaphragm seal (HTDS). Typical high-temperature applications include the chemical, petrochemical, and molten salt thermal solar industries.

Some applications require custom diaphragm seals. We've developed seals that can withstand extreme process conditions, or diaphragm seals that require custom-designed connections.

BF type seal

Art. BF

The BF design features a seal housing made from a forged blind flange. The welded joint between the diaphragm and the seal housing is the wetted part, so the diaphragm materials are generally the same as the flange material. The BF is typically used in conjunction with differential pressure sensors for applications such as level, flow, and absolute pressure measurement.

The diaphragm is TIG-welded to the flange and designed to provide the best performance for a specific size. This means its flexibility and shape are carefully tested and measured. The standard membrane foil thickness is 0.075 mm.

Gas-filled thermometer BDTG18

Art. BDTG18

The Badotherm BDTG18 thermometer is available in 100/160 mm diameters. The BDTG18 is available with various connections, including fixed stem, capillary, or leather. These gas-filled thermometers are suitable for aggressive environments and those found in the chemical, petroleum, and food industries.

A bimetallic thermometer's measurement method involves the expansion of two different metals. These two inseparable, connected metal strips have different coefficients of thermal expansion. The bimetallic system is integrated into the thermometer stem and functions as a temperature sensor. An inert gas-filled thermometer's measurement method involves the expansion of the gas in a closed system. Changes in the temperature of the process being measured create a change in pressure in the measuring system, which is converted into a correct temperature reading on the dial. This type of thermometer is available as a direct mount or capillary thermometer.

Contact pressure gauge BDT30

Art. BDT30

The Badotherm BDT 30 under-dial pressure gauge is manufactured according to EN837-1/DIN 16085 and is available in fully wetted stainless steel or alloy 400. This pressure gauge is typically used in applications in the chemical, petrochemical, oil and gas, power and utility industries, mechanical engineering, and general process industries. Safety is paramount, thanks to a blow-out function, pressure elements made of high-quality tubing, and a welded connection design. These gauges are designed to withstand the harshest environmental conditions.

Range and accuracy capabilities are determined by the dial size. Accuracy ratings are based on dry gauges. Filling with liquid may affect accuracy.

Badotherm BDT18 process pressure gauge

Art. BDT18

The Badotherm Model BDT18 pressure gauge is manufactured in accordance with EN837-1 and is available in stainless steel or Alloy 400. This pressure gauge is typically used in applications in the chemical, petrochemical, oil and gas, power and utility, mechanical engineering, and general process industries. Safety is paramount, thanks to a blow-out function, pressure elements made of high-quality tubing, and a welded connection design. These gauges are designed to withstand the harshest environmental and process conditions.

Range and accuracy capabilities are determined by dial size. A reduced-volume version is specifically designed for use with diaphragm seals. Accuracy ratings are based on dry gauges. Filling with liquid may affect accuracy.

Control and measuring instruments

Control and measuring instruments (CMI) are specialized devices designed to measure specific physical quantities. They perform important functions, allowing equipment to be monitored and adjusted based on the data collected. CMI are used in various industries, including construction, manufacturing, and utilities.

Purpose of control and measuring instruments

The primary purpose of control and measuring instruments is to measure physical quantities. They allow monitoring of parameters such as pressure, temperature, electrical parameters, and others. The data obtained helps equipment operators monitor its performance, conduct maintenance, and make necessary adjustments.
